Wiring is inevitable because of those thick walls. Wireless signals cannot travel pass them. (I actaully have to position my phone pointing to corridor in order to use WiFi in my bedroom. No signal at the bed side of the room.)
Fair enough, but that doesn't mean there's a lot of other people who do. I'm just thinking that there's no way to plug an iPad into a wired network, but that doesn't seem to causing too much of a problem.
